Exchange the Processing Sequence identifier

Before calling function DXP1FN1, your application must place the Processing Sequence identifier on the exchange list using the EXCHANGE RDML command:

NOTE:  Function DXP1FN1 can receive the values of other fields with names beginning with 'DX' from the exchange list.  Your application does not need to (and should not) exchange these other fields.  To avoid interfering with the correct behavior of function DXP1FN1, you should NEVER exchange any fields with names beginning with 'DX' before the call, other than the fields explicitly described here.

For an example of exchanging the Processing Sequence identifier before calling function DXP1FN1 refer to:
